No harm in having the test. These measurements have a pretty big margin of error but it would be bad to have undiagnosed gestational diabetes so I'd have it. I can't stop drinking water so thinking of asking for one just to rule it out.
Yeah I was way above the red line on the chart though so not just out of range x
my bump was massive because i had a lot of fluid, they were convinced baby was about 8lbs when i was 34 weeks, so planned on inducing me at 38, baby came earlier and was only 6lbs1😅 all these scans are guesses really they can’t be super accurate so try not to worry
